MACHINE FOR GROOVlNG LUMBER.

SPECIFICATION forming part of Letters Patent No. 396,399, dated January22, 1889.

Application filed June 14, 1883- Serial No. 277,104. (No model.)

To aZZ whom it may concern.-

Be it known that I, J ULIAN T. GRzrBowsKI, a citizen of the UnitedStates, residing at Grand Rapids, in the county of Kent and State ofMichigan, have invented a new and useful Improvement in Machines forGrooving Lumber, of which the following is a specification.

My invention relates to an improvement in lo machines for groovinglumber; and it consists in the peculiar construction and combination ofdevices, that will be more fully set forth hereinafter, and particularlypointed out in the claims.

The object of my invention is to provide a grooving-machine which isadapted to be con nected directly to the discharge end of a planing ormatching machine and to be operated by a belt driven by thedriving-pulley of the planing or matching machine; and a further objectof my invention is to provide a grooving-machine with guide-pulleys fordirecting the lumber under the cutters as it leaves the planer ormatcher, and to provide shields whereby chips or shavings are preventedfrom getting between the said pulleys or rollers and the board which isbeing grooved.

In the accompanying drawings, Figure 1 is a side elevation of agrooving-machine embodying my improvements, showing the same attached toa planing-machine. Fig. 2 is a top plan view of the grooving-machine.Fig. 3 is a detail sectional view taken on the line 000: of Fig. Fig. Iis a vertical sectional view of my grooving-machine, taken on the line yy of Fig. Fig. 5 is a similar view taken on the line .2 z of Fig. 2.Fig. 6 is a detail elevation of one of the shields.

A represents a planing or matching machine, which is of the usualwell-known construction, and is provided at its front end with the usualdriving-shaft, B, having the driving-pulley C.

D represents the bed-plate or table of my improved grooving-machine, inopposite sides of which are secured ve1'tically-adjustable standards E,having bearings F pivoted in their upper ends and adapted for theattachment of the oppositely-inelined shafts G, having the cutters H.Said standards, bearings, and inclined shafts are of the sameconstruction as those described in my pending application for LettersPatent of the United States, Serial No. 253,989, filed November 1, 1887,and hence are not more fully described herein. In 5 5 the upper side ofthe bed or table, near the front and rear sides thereof, aretransverseT-shaped grooves I.

K represents bolts, which have their heads fitted in the said groovesand guided therein, the upper end of the bolts projecting above the topof the table or bed, and there being two of the said bolts in eachgroove near opposite sides of the table or bed. On each bolt is fitted:a cylindrical sleeve or bushing, L, which bears upon the top of thetable or bed, and on each of the said bushings or sleeves is journaled ahorizontal roller, M, ofv suitable size.

' Clamping-nuts N are screwed to the upper ends of the bolts K and bearupon the bushings, the function of the said clamping-nuts being tosecure the bolts rigidly in the grooves at any desired adjustment, andthe function of the rollers M being to bear against the op- 7 5 positeedges of the board as the same is discharged from the planing ormatching machine and is grooved by my improved grooving-machine, thesaid rollers guiding the said board over the table or bed D. Midwaybetween the grooves I is a similar T-shaped groove, 0.

P represents a pair of brackets or standards, which are provided attheir lower ends with outwardly-extending horizontal arms R, which bearupon the table or bed. Clamping-bolts S have their heads fitted andadapted to slide in the groove 0 and serve to clamp the standards P tothe table-top at any desired distance apart. The vertical portions ofthe said standards or brackets are provided each with a vertical slot,S, and a vertical slot, T, the latter being in line with and above theformer.

U represents a pair of rollers which are similar to the rollers M, arearranged in a vertical position, and are journaled on spindles 5 V, theouter ends of which extend through the slots S and are provided withclampingnuts \V', whereby the said spindles may be secured at anydesired vertical adjustment, and consequently enable the rollers U to bevertically adjusted and adapted to bear upon the upper sides of theboards which are being grooved. The function of these rollers is to keepthe board bearing snugly on the bed or table while the grooving-cuttersare in operation, so as to cause the grooves to be cut in the boardthroughout the entire length thereof at a uniform depth.

It is essential to the perfect operation of the grooving-machine thatchips and shavin be prevented from being caught between the rollers Uand the board; and to this end I provide a pair of horseshoe-shapedshields, X, which are arranged over the rollers U and are provided attheir upper ends with ears Y. Clamping-bolts Z pass through openings inthe said ears and through the vertical slots T and serve to secure theguards to the stand ards at any desired adjustment. The lower ends ofthe guards are provided with feet A, as shown, which feet bear againstthe upper side of the board which is being grooved and serve to preventchips or shavings from passing under the rollers U. From the front sideof the table or bed project a pair of brackets or arms,l3, which havetheir inner ends secured to the under side of the table or bed by meansof bolts 0. The outer ends of the brackets are provided with splitbearings D, having lugs or ears E, and clamping-bolts I extend throughthe said lugs or cars, as shown.

G represents a pair of brackets or plates, which are secured to oppositesides of the frame of the planing or matching machine, at the rear endthereof, by means of bolts II. The said brackets or arms are provided attheir outer ends with transverse openings, and a shaft or pintle-rod, 1,extends through the said openings and through the split bearings D ofthe grooving-machine, and serves to hinge or pivot the grooving-machineto the rear end of the planing or matching machine, so that saidgrooving-machine may be turned to a horizontal position when it isdesired to use it, and may be folded down on the rear end of the planingor matching machine, where it will be out of the way when it is notdesired to use the grooving-machinc. By reason of the split bearings Dand the clamping-bolts I with which their lugs are provided, thegrooving-machine may be clamped to the pintle shaft or red at anydesired lateral adj ustment.

The grooving-machine is provided near its outer side with a telescopicor sliding leg, K, by means of which the bed or table may be supportedin a horizontal posit-ion and extended from the planer or matcher.

In order to drive the inclined shafts which carry the cutters, I journala counter-shaft, L,in openings near the rear end of the frame of theplaner or matcher, and provide the said counter-shaft with pulleys M,which are connected to the pulleys on the inclined shafts by means ofendless belts N, and also pro vide the said counter-shafts with apulley, O,

which is connected by a third endless belt,

P, to the driving-pulley C of the planer or matcher.

From the foregoing description it will be understood that mygrooving-machine is exceedingly compact, so as to take up very littleroom, and that it may be very readily arranged for operation anddisconnected from the planer or matcher.

a a represent openings made in the opposite corners of the front side ofthe table. b designates a shield having depending legs 0 at its endsdesigned to fit in the openings (t a in the table.

The shield is to protect the operator from being struck by pieces of themachinery in case the machine should break.
